IMPROVEMENT IN CHAIN-LINKS.

Specification forming part of Letters Patent No. l 69,731, datedNovember 9, 1875 application led October 16, 1875.

To all whom t may concern:

Be it known that I, WILLIAM ROEMER, of Newark, in the countyT of Essexand State of New Jersey, have invented a new and useful Improvement inChains, of which the following is a specification:

Figure l is a face view of my improved chain. Fig. 2 is a longitudinalcentral section of the same. Fig. 3 is a face View ofthe blank for oneof the links. Fig. 4 is a central section thereof in the line c c, Fig.3.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to an improvement in that class of chains inwhich the contiguous links are connected by an eye that is fastened toone link and loosely embraces the other.

Heretofore, in such chains, each eye was formed of a separate strip ofmetal, riveted or soldered at both of its ends to the link with which itwas to be connected.

My invention consists in making the link and the eye in one piece, sothat only one end ofthe strip forming the eye need be riveted to thelink.

The letters A A A in the drawing represent a series of links composingmy improved chain. These links may be made of metal, hard rubber, orother material, and are of annular or suitable form. Each link A isprovided and made in one piece, With a projecting strip, a, which, inthe drawing, is shown to project from the inner edge of the annular linkdiametrically across the hole in the link, but

which has its outer end disconnected to allow it to be bent, ashereinafter described. Each of these strips a is bent backward-i. ef.,doubled over-and the eye thus formed is made to embrace the next link ofthe chain. The free end of each strip a is thereupon riveted by a rivet,d, or otherwise fastened to the face of the saine link on Which it isformed.

The ends ofthe chain may be provided with hooks and eyes B, or othersuitable fasteningdevices.

By the above construction the strength of the chain is greatly increasedand its appearance improved, as each link Will be perfectly smooth onone face, which in use should be the outer or exposed face.

By this invention, also, material is saved, as the strip a is `aboutone-fourth shorter than it must be Whenever it is not made as part ofthe blank. I

This chain, made according to my invention, may be used for all thepurposes for which chains are or may be now employedsuch asWatch-chains, belts, Src.

I claim as my inventionu A chain-link, A, made in one piece with theprojecting strip a, which forms the eye for joining the contiguous link,substantially as described.

The foregoing description of my invention signed by me this 15th day ofOctober, 1875.

WILLIAM ROEMER.
